Retrospective cohort study. ⋯ The incidence of lumbar curve adding-on was 6.2%. Patients who were hypokyphotic and skeletally immature are nine times and six times more likely to have lumbar adding-on, respectively. This article examines adding-on in patients who had either anterior or posterior approach scoliosis surgeries, with follow-up stretching up to 10 years. This offers the rare opportunity to examine the natural history of the adding-on phenomenon.Level of Evidence: 3.

Experimental in-vivo animal study. ⋯ This study demonstrates that a combination of AI-derived image processing and machine learning algorithms can be developed to enable real-time ultrasonic detection, segmentation, classification, and display of critical anatomic structures, including neural tissue, during spine surgery. AI-enhanced ultrasound imaging can provide a visual map of important anatomy in and adjacent to the psoas, thereby providing the surgeon with critical information intended to increase the safety of LLIF surgery.Level of Evidence: N/A.

Multicenter Study
One Year Outcomes From a Prospective Multicenter Investigation Device Trial of a Novel Conformal Mesh Interbody Fusion Device.
A prospective multicenter investigational device exempt trial is underway evaluating a novel conformable mesh interbody fusion device in subjects undergoing single-level fusion for degenerative disc disease. Patients meeting inclusion and exclusion criteria were offered enrollment. There is no comparative group in this study. ⋯ 12-month outcomes demonstrated excellent patient compliance and positive outcomes for pain, function, fusion, and device safety. Clinical improvements were observed by 6-weeks post-op and appear durable up to 1 year later. A novel mesh interbody device may provide an alternative means of interbody fusion that reduces connective tissue disruption.Level of Evidence: 3.

Prospective cohort study. ⋯ The PROMIS-29 scale scores assessing pain intensity, physical function, and anxiety evidenced the most responsivity in the study sample. The results, when considered in light of the findings from other investigators, support 5.0 points as a reasonable MCID for most of the PROMIS-29 scales. Further studies are needed to determine the generalizability of the findings.Level of Evidence: 2.

A 2-year follow-up review of 62 patients with severe rigid scoliosis (>120°). ⋯ For severe rigid scoliosis with a Cobb angle greater than 120°, a combination of short-term presurgical HPT and posterior surgery is an effective and safe solution. After 4 to 6 weeks of presurgical HPT the Cobb angle can be decreased by approximately 50%, providing a favorable condition for spine corrective surgery.Level of Evidence: 3.
